Grey wolves, from whom domestic dogs evolved, don't eat carbohydrates. They never did. They are carnivores. But the suggestion that wolves might have eaten peas, no less 'pea protein' and potatoes....
Just that may certainly be implied in Blue Wilderness ads, calling its dog food, "Nature's Evolutionary Diet." Especially when a dog, whose owners are convinced by advertising that their boy's food is "... [i]nspired by the diet of wolves” and is otherwise consistent with dogs’ “ancestors in the wild.” Defendant’s Blue Wilderness packaging prominently displays an image of a grey wolf and promotes these products as “Nature’s Evolutionary Diet.” (source)
Truth About Pet Food, Susan Thixton's consumer advocacy newsletter, obtained a copy of the law suit, in which the plaintiffs argue that Blue Buffalo's claims are, at the very least, misleading (if not lies). For example, the plaintiffs allege:
- That the Blue Wilderness diet does not represent the diet of wild wolves: "Wild wolves consume little or no dietary carbohydrate and they do not experience high rates of chronic diseases such as obesity and cancer. In fact, these diseases are essentially non-existent in wolf populations."
That the diet's contents do not represent the "evolutionary diet" of wolves, but that the contents "contain high levels of dietary carbohydrates, which are neither healthy for dogs nor a meaningful part of the diet of grey wolves."
- That the high dietary carbohydrate content of Blue Wilderness foods contribute to a variety of serious illnesses in dogs, including diabetes, heart disease, and cancer. (source)
From a consumer advocate's perspective, the suit eloquently expresses the failings of the pet food industry to invest in scientifically-supported claims and to use science to create truely healthy food for our pets. If you are a dog parent, it would be a good idea to read the entire law suit here. (It doesn't take long to read.)
